摘要
为了研究饲料中酵母培养物(Yeast culture,YC)代替等质量鱼粉对异育银鲫生长性能和生理健康的影响。在含豆油(正对照)、氧化豆油(负对照)的基础饲料中分别以0%、1%、2%、3%的YC替代等质量的鱼粉,分别记为S、SC1、SC2、SC3、O、OC1、OC2、OC3,在池塘中养殖异育银鲫[初始体重为(7.08±0.01) g] 65 d。养殖实验结束后,用异育银鲫CyHV-2病鱼内脏组织液对各实验组鲫鱼进行攻毒实验。结果显示:SC1、SC2、SC3组与S组比较,SGR和FCR无显著差异(P>0.05)。O组与S组比较,SGR下降6.53%(P<0.05);FCR提高16.27%(P<0.05)。O组结果比较:OC1、OC2、OC3组SGR均提高(P<0.05),FCR均下降(P<0.05)。各组血细胞和血清指标发生一定程度的变化。攻毒实验结果显示,与S组比较,SC1、SC2、SC3组累积死亡数降低;与O组比较,OC1、OC2、OC3组累积死亡数也降低。本实验结果表明,1)在基础日粮鱼粉为12%的条件下,用1%~3%YC替代等质量的鱼粉具有一定的可行性。2)氧化豆油会导致异育银鲫氧化损伤。3)在含有氧化豆油的日粮中,饲料YC可以一定程度修复氧化损伤。4)本实验条件下,饲料YC可以增强异育银鲫免疫防御能力、抗氧化损伤的能力,综合表现为对CyHV-2病毒攻毒保护具有较好的效果。
In order to study the effect of the growth performance and physiological health on gibel carp(Carassiusauratusgibelio) by replacing fish meal with equal quality yeast culture(YC) in feed. In this study, 0%, 1%, 2% and 3% YC were used to replace fish meal of the same quality in the basic feed containing soybean oil(positive control) or oxidized soybean oil(negative control), recorded as S, SC1, SC2, SC3, O, OC1, OC2, OC3, respectively. The diets were fed quadruplicate groups of gibel carp [initial body weight(7.08±0.01) g] for 65 days in outdoor farming system. After breeding experiment, each group fish was challenged by injecting visceral tissue fluid obtained from the gibel carp with CyHV-2 virus. The results showed that: Compared with group S, the SGR and FCR of group SC1, SC2, SC3 was not significantly different(P>0.05). Compared with group S, the SGR of group O fell by 6.53%(P<0.05), the FCR of group O increased by 16.27%(P<0.05). Compared with group O, the SGR of group OC1, OC2, OC3 both increased(P<0.05), and the FCR of group OC1, OC2, OC3 both decreased(P<0.05). The blood cells and serum indicators of each group changed to some extent. Attack test results showed that: Compared with group S, the cumulative deaths of group SC1, SC2, SC3 reduced. Compared with group O, the cumulative deaths of group OC1, OC2, OC3 reduced, too. The results of this test indicated that: ①In the case of basal diets containing 12% fishmeal, it was feasible to replace the same quality fishmeal with 1%~3% YC. ② Oxidized soybean oil caused oxidative damage. ③In diets containing oxidized soybean oil, adding YC could repair the damage to a certain extent. ④Under the conditions of this test, diet YC could enhance the immune defense ability and anti-oxidative damage ability of gibel carp, and it is reflected in supportive effect in the protection of CyHV-2 virus.
